There's word that a polar bear at the Seneca Park Zoo in Rochester is expecting.. at least that's what zoo officials think. They say there is no pregnancy test for polar bears, but the signs are there, and it is possible that the bear, named Aurora, will give birth around Thanksgiving.

Officials say this was accomplished with the world's first artificial fertility process for polar bears .

Aurora has had four cubs already, the last one in 2002... the male polar bear at the zoo is named Zero...he's never fathered cubs up to now.
